Codeforces Global Round 10 should be unrated for the following reasons:

  1. Long queue: the queue was really long (up to 20 minutes)! Imagine submitting a solution for problem A at 0:05 and receiving the verdict "runtime error on test 2" at 0:25 because of a silly out of bounds: it's really unfair!

  2. Weak pretests on problems A and B: this is a critical issue of the contest, because more than 20000 submissions on problems A and B passed the pretests! Among these, about 1000 solutions were hacked and more than 1000 solutions failed system tests (more than 2000 people have been affected). Even the model solution was wrong!

  3. Also, the leaderboard has been messed up by the enormous number of hacks (hacking 6 people can be worth more than a problem); hacks are unfair because not everyone has the same chances, since some rooms have more wrong solutions than others.

  4. Wrong order of problems: the problem F was extremely easy, in fact it was proposed as a B (it's written on the editorial). So, people that were not able to solve E had a significant advantage, since they had the opportunity to try the easy problem F and get a lot of points.

It's obvious that Codeforces Global Round 10 should be unrated!

I think there is only one reason: You did bad in that contest from your original account.

DISCLAIMER: This reply is intended for the newcomers and not the trolls.

None of the problems violate the propositions of the contest. I mean, nobody is forced to tell you E is harder than F. Many times D is easier than C, this time C was as easy as A and perhaps slightly easier than B, so I don't see anything wrong with F. You are always kindly asked to read all the problems.

As for the hacking phase, it's never completely fair, this round is not specific in that regard. After all, 50 people taking hacks won't really decrease your ranking by more than 50 places, and in case you are top 300-400, chances are hacking A or B won't be enough to surpass you.

Weak pretests, many time they are rather weak, but again this is not something stated in the propositions.

Conclusion: The points made in the blog are bullshit, I guess everyone is aware of it, so no changes soon I guess.
